Pi questions for Eric Foster.
I am a keen nugget hunter from Australia. Despite the obvious progress in the evolution of detectors for nugget hunting I am painfully aware of their limitations in our high ferrite soils. These limitations are principally but not limited to, very significant loss of depth and sensitivity compared to low ferrite soils, failure to detect some kinds of nuggets and specimens and despite the much touted Minelab DVT technology very significant interaction with ground ferrites and other minerals. This interaction is reflected as phantom signals which increasingly display the characteristics of metallic targets. The sensitivity of the latest generation of Minelab Pi detectors seems to have been improved but with minimal or no improvement in signal to noise, in fact the latest detector seems more subject to Rf and stray magnetic fields interference than previous models.
My question, are their any new Pi platforms on the horizon or methods that may give us some hope of overcoming these limitations and give us a Pi detector that can go deeper on nuggets in these high ferrite soils? Is it possible for example to shift the amplitude frequency distribution of the broadband Tx signal to much lower frequencies(2-10Khz) which being longer wavelengths would penetrate deeper on larger targets? Even a modest improvement of say 20% in depth on larger nuggets would have a very dramatic impact.
There is I believe at least in Australia a very significant market for such a Pi platform which is not being satisfied by any current manufacturers. I would be most interested in your thoughts. Perhaps you could think about a goldscan 6 specifically for this purpose?
Best Regards
